This data storage converter uses 1024 as the conversion factor between each unit (1 KB = 1024 bytes, 1 MB = 1024 KB, and so on), the binary standard used by operating systems for file sizes and memory. Your input is converted to bytes first, then converted into your target unit.
Storage device manufacturers typically advertise capacity using 1000 as the conversion factor (the decimal standard), while your computer's operating system displays file and drive sizes using 1024 (the binary standard). This is why a drive advertised as 1 TB often shows a slightly smaller capacity, around 931 GB, when viewed on your computer.
Converting 1 gigabyte to megabytes gives exactly 1,024 MB, and converting 1 GB down to bytes gives 1,073,741,824 bytes (1024³), using this tool's binary (1024-based) convention throughout. That's why a manufacturer's '1 TB' drive, advertised using the decimal (1000-based) convention, shows up as roughly 931 GB once your operating system reports it using the binary convention this tool matches.
Assuming a device's advertised capacity (typically 1000-based) will match exactly what your OS reports (1024-based), the two conventions diverge more as the numbers get larger, a 1 TB drive genuinely shows less than 1024 GB of usable space under the binary convention.
Mixing up bits and bytes, this tool clearly separates the two, but it's easy to misread 'Mb' (megabits, often used for network speeds) as 'MB' (megabytes, used for file sizes), an 8x difference.
Assuming this tool matches network speed conversions, bandwidth and transfer rate figures are conventionally decimal (1000-based, like our Bandwidth Calculator and Digital Transfer Rate Converter use), while storage capacity here uses the binary (1024-based) convention, don't mix the two conversion factors.
This calculator uses 1024 as the conversion factor between units (the binary standard commonly used by operating systems), rather than 1000 (the decimal standard sometimes used by storage manufacturers), which is why file sizes can appear slightly different between your OS and a drive's advertised capacity.
Manufacturers typically advertise storage using the 1000-based decimal system, while operating systems display it using the 1024-based binary system, causing an apparent (but explainable) discrepancy.
